  1. Results of the analyses of the series of spectra containing two overlapping target peptides. The first column contains the m/zpositions and the charges (in brackets) of the two peptides. The two middle columns indicate whether the corresponding problem is successfully solved (‘x’) or not (‘−’) when optimizing over a grid of parameter combinations (column ‘all’) and when using the default parameter set (column ‘default’).
